The Builder provides a convenient interface for inserting instructions
into an extended basic block.
The bulk of the builder methods are generated automatically from the
meta language instruction descriptions.
Still TODO: Keep track of an insertion position.
In instruction formats that have multiple results AND boxed storage,
place the second_result field outside the boxed storage. The 16-byte
instruction format has room for opcode, type, second_result in the first
8 bytes, and the boxed pointer in the last 8 bytes.
This provides a simpler implementation of the second_result() and
second_result_mut() InstructionData methods.

The Rust type is usually the camel-cased name of the operand kind, but
there are variations, so allow an explicit rust_type='IntCC' when
defining operand kinds.

These refer to external functions and function signatures declared in
the preamble. Since we're already using the type names 'Signature' and
'Function', these entity references don't folow the usual EntityData /
Entity naming convention.

Entity references in instruction format operands also have member names
in the InstructionData struct. Track them the same way we track immediate operand member names.
Value operands still go in the arg / args members.

Enable syntax: iadd(x, y) which creates an Apply node.
Enable syntax: z << iadd(x, y) which creates a Def node.
Add an XForm class which represents source and destination patterns as
RTL lists.

The isplit_lohi instruction breaks an integer into two halves. This will
typically be used to get the two halves of an `i64` value on 32-bit
CPUs.
The iconcat_lohi is the reverse operation. It reconstructs the `i64`
from the low and high bits.
